IMPROVEMENT IN ENVELOPES.

Specification formin g part of Letters Patent 1510-1744140, dated March 21, 1876; application filed July 24, 1875.

To all whom it may concern Be it known that I, HENRY E. BROWN, of I ronton, in the county of Lawrence and State of Ohio, have invented anew and Improved Letter-Envelope, of which the following is a My invention consists of an extra back atiachment for envelopes, so contrived that the writers name may be written on one and ioncealed by the other, leaving the name of the party addressed so that, in case the latter iails to get thelet-ter, the address of the contents of the letter, ready for re-mailing the letter to him, by tearing off the outside address, so as to apprise the writer of the failure of his letter to reach his correspondent, and save the Post-()ffice Department the trouble and expense of sending letters to the Dead- Letter Office. I

This extra back may be separately made and lightly pasted on the true back at both unis, but a more preferable way is to out out the envelope so that it forms a prolongation of one of the under parts, and folds over at and around one end on the back, and pastes down at the other end, which will have one corner out so that the stamp will paste on the Figure 1 is a perspective view of an envelope having the extra back to fold over the ordinary back, whereon the name and address or the writer is placed, to be covered by the extra back having the name and address of the party for whom the letter is intended. Fig. 2 is a perspective view showing the extra both ends.

back having the name and address of ,the one to whom the letter is to be sent. Figs. 3 and 4 are elevations of Figs. 1 and 2.

Similar letters of reference indicate corresponding parts.

A is the ordinary back of the letter, having the name and address, B, of the sender; also, having the stamp 0. D is the extra back, having the address of the party for whom the letter is intended, also having one corner cut so as not to cover the stamp, and also having the inner side of the free end pasted at F to stick fast to the back A, as in Fig. 3.

This extra back is, in this example, made in prolongation of the flap G, so as to fold around one end, overthe back A, thus enabling it and the rest of the envelope to be cut out in one piece of paper, but it may be made separate from the envelope and pasted on at At one end should be printed instructions, as at H, to the postmaster to tear off the extra back for bringing out the address of the writer, in case the letter is not called for or delivered.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent- An envelope having extra back D, with excision E, as well as pasting-edge F, andconnected by piece G with the ordinary back A, as shown and described.
